Whether you wish to camouflage or decorate your garden wall, you can find plants to do the job. Trailing vines planted at the top of the wall can drape gracefully in front of a stone, brick or concrete wall. Other plants are climbers and should be planted in the ground at the base of the garden wall so they can grow their way to the top.
Plant a honeysuckle vine to trail along your garden wall. Honeysuckle plants boast sweet, trumpet-shaped flowers. With over 180 different varieties to choose from, you can plant honeysuckle that is evergreen or deciduous and hardy in USDA zones 5 to 8. Honeysuckle plants enjoy full sun or partial shade, depending on the species.
Clematis is another vine-type plant that can grow beautifully on a garden wall. Most of the 250-plus species of clematis are deciduous, but a few are evergreen and a few others are herbaceous. Though the vines are not very attractive during the winter months, they burst with colour during the spring with flowers that can measure up to 10 inches in diameter. Some species can have up to 100 blooms per plant during the season. Clematis vines prefer full sun and are hardy to zone 3.
If you prefer evergreen foliage, plant the English ivy "Hedera helix" along your garden wall. Among the hundreds of Hedera helix cultivars, be sure and select a species that is cold hardy to your planting zone. The shape and colour of the leaves vary by cultivar; many species are drought resistant.
Plant creeping thyme along the top of a garden wall for cascading evergreen foliage and colourful flowers in the late spring and early summer. Creeping thyme is a compact, low-growing plant that flowers in shades of lavender, rose, white or red. Hardy in zones 4 to 9, creeping thyme plants grow well in full sun to full shade, but the growth and the flowers are not as prevalent in the shade.
Passion flower, also known as maypop, is a flowering vine plant that is considered hardy in zones 5 to 9. The vine boasts 3-inch diameter flowers that begin blooming in July and can continue blooming until frost. In their preferred partial to full sun, the passion flower vines can grow up to 15 feet during one season.
